How do social divisions affect politics? Give two example.

In a democracy, there is competition among political parties to win elections and from government. Their object is to gain political power. The competition among political parties divides the society. Already existing social divisions may become political divisions. Elections are fought on the basis of social divisions. Parties seek votes and support of social divisions at the time of elections. Candidates are selected on the basis of social divisions in a constituency  to attract maximum voters. A Muslim or Hindu fights elections in a Muslim or Hindu dominated constituency. Parties too try to attract votes on the basis of social divisions. For example, Bahujan Samaj Party seeks the votes of Dalits in India. Its base is dalit vote bank. In Northern Ireland, 53 per cent are Protestants and 44 per cent Roman Catholics. The Northland Ireland be unified with the Republics of Ireland. On the other hand, Protestants were represented by unionists who were in favor of remaining with the UK This led to violent conflicts and ultimately in 1998, the UK government  and the Nationalists reached a peace treaty. In Yugoslavia too, combination of  political and social divisions led to disintegrations. Thus, social divisions affect politics and many have disastrous consequences.
